This invention relates to windows and to weather strips for windows.

It is a common practice to weather strip windows with sheet metal strips fastened to 5 tne window frame, the sashes being grooved to take said strips. lVhen strips of this character are properly installed they are fairly satisfactory, but they are very liable to be come sprung, bent, or loose, and they then come to be a positive nuisance. The present invention aims to improve both window and weather strips for them with a view to providing a sturdy and more substantial construction than has been used heretofore, fa-

cilitating the installation of such strips, and eliminating the usual wooden parting strip on double hung windows. 1

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawing, and the novel features will be particularly pointed out in the appended claim.

In the drawing,

Figure 1 is a perspective view of a portion of a window of the double hung type and of a frame therefor, and also illustrates a weather strip construction embodying this invention;

Fig. 2 is a perspective view on a larger scale of the weather strips used in the window illustrated in Fig. 1;

Fig. 3 is a horizontal sectional view through the window illustrated in Fig. 1; and

Fig. L is a view on a larger scale of the weather strip construction shown in Fig. 3. Referring first to Figs. 1 and 3, the construction there shown comprises a window 40 frame including a jamb 2, inner and outer frame pieces 3 and 4, respectively, and a sill 5. The upper sash is indicated at 6 and the lower sash at 7. This is a common and well known construction. I

The weather strip provided by this invention is better shown in the upper part of Fig. 2 and in Fig. 4. It includes a channel section or bar 8 provided with an integral angular section or strip 9. The bar 8 has two parallel flanges a and 6, while the angular section in- ,allel to each other.

cludes a flangec which is connected to the flange Z) by a web .cZ. In the preferred arrangement the edge of the flange 0 extends in a direction opposite to'theedges of the flanges a and b but all three of these flanges are par- It'will be observed that the web cl is connected to thei-flange b at an intermediate point in the width of the flange. Also, that the extreme edge portion of the flange c is thickened and rounded.

The usual stock window jamb 2 is always. provided with a groove 10 to receive the ordinary Wooden parting strip which separates the guideways for the upper and lower sashes. strip provided by thisinventi on takes the place The channel bar 8 of the weather of this parting strip, the inner portions of the flanges a and b fitting tightly in the groove 10. Preferably the edges of these flanges are bevelled, as shown at e, to facilitate the entrance of this edge of the bar into the parting strip groove. Several holes are punched through the web at and countersunk to receive wood screws 12 which are driven into the jamb 2 and serve to hold the weather Stripsecurely in its operative position.

A groove 14' is made in that surface of the sash 6 which normally runs against the jamb 2 to receive the flange 0. Consequently, a tongue f of the sash is provided along its in ner edge which runs in the groove between the-flanges b and 0. This closes the joint around the sash effectively against the entrance of any substantial amount of air, even under high winds, while the thickened edge of the flangereduces the friction between the sash and the Weather strip.

The upper part of Fig. 2 illustrates the weather strip arrangement for the upper sash. In applying this strip to the'lower sash it issimply necessary to turn it end for end so that the angular section 9 will project inwardly instead of outwardly. In other respects this strip is installed and the lower sash fitted to it in exactly the manner above described in connection with the upper sash. I

We have found that a weather strip'of this construction can be made economically from non-corrosive metals such as aluminum,

true and regular, a window equipped Withthese weather strips offers practically no in creased resistance to opening or closing.

WVhile we have herein shown and described a preferred embodiment of our invention, it

- will be understood that the invention may be embodied in other forms without departing from the spirit or scope thereof.

Having thus described our invention, what we desire to claim as new is:

A weather strip for windows comprising an extruded metal bar of channel shape in cross-section adapted to enter the parting strip groove in a window jamb and to serve as a parting strip for the window, the edge of said barbeing bevelled to facilitate its entrance into said groove, and an angular strip integral with said bar and comprising a web extending laterally from one flange of said bar at a'point intermediate in the width of said bar and a flange at the outer edge of said web extending at right angles to the web and parallel to the flanges of said bar, the free edge of the flange of said angular strip being thickened and rounded and being directed oppositely to the flanges of said bar and lying approximately flush with the outer edge of said channel bar.
